基于农艺性状和产量指标的大豆净作筛选研究

Study on Net Soybean Cropping Screening Based on Agronomic Traits and Yield Indicators

文章以8个巴中地区当地大豆品种及4个引进大豆品种为研究对象,对其农艺性状和产量指标进行净作品种比较试验,筛选适宜巴中地区种植大豆品种。结果表明,引进大豆品种外观品质、百粒重及产量均优于当地品种。其中巴中地区当地大豆品种表现为生育期短、百粒重小、有效荚粒比大、产量低;引进大豆品种表现为生育期长、颗粒饱满、百粒重大、产量高。当地大豆品种中,220302综合表现优良,有效荚粒比为0.61、百粒重为19.6 g,产量为1818.00 kg/hm^(2)。12个大豆品种中,引进品种齐黄34号综合表现优良,有效荚粒比为0.45,百粒重为24.23 g,产量为2034.75 kg/hm^(2),可替代当地大豆品种作早熟大豆在巴中地区推广种植。

The article took eight local soybean resources and four introduced soybean varieties in Bazhong region as the research objects,conducted a comparative experiment on their agronomic traits and yield indicators of net crop varieties,and selected suitable soybean varieties for planting in Bazhong region.The results showed that the appearance quality,100-grain weight and yield of introduced soybean varieties were superior to local soybean varieties.Local soybean in Bazhong area had short growth period,small 100-grain weight,large effective pod grain ratio and low yield,introduced soybean varieties had long growth period,full particles,big 100-grain weight and high yield.Among the local soybeans varieties,the comprehensive performance of 220302 was good,the effective pod grain ratio was 0.61,100-grain weight was 19.6 g,and the yield was 1818.00 kg/ha.Among the 12 soybean materials,introduced soybean varieties Qihuang 34 showed good comprehensive performance,with an effective pod ratio of 0.45,100-grains weight was 24.23 g,and the yield was 2034.75 kg/ha,which was suitable for promoting the planting of early maturing soybeans as a substitute for local soybean varieties in Bazhong area.
